Hengyang Heavy Industry Safety Brake SBD160-A Interlock Protection

Depending on the mounting position, brakes can be classified as wheel brakes and centre brakes. Brakes in which the rotating element is fixed on the wheel or half-shaft are called wheel brakes; brakes in which the rotating element is fixed on the drive shaft of the transmission system are called central brakes. Wheel brakes are generally used for service brakes, but also for emergency brakes and parking brakes; the central brake is generally used only for parking brakes and slow brakes.

According to the different rotating elements, friction brakes can be divided into two categories: drum and disc. The rotating element in the friction pair of the drum brake is the brake drum (brake drum), with its cylindrical surface as the working surface; the rotating element in the friction pair of the disc brake is the disc-shaped brake disc (brake disc), with its end face as the working surface.

Disc brakes are divided into caliper disc brakes and full disc brakes according to the different structural forms of their fixed elements. The fixed element and rotating element of the friction pair of the full disc brake are disc-shaped and are called fixed disc and rotating disc, respectively. All the working surfaces of the disc can be in contact with the friction pads at the same time, and its structural principle is similar to that of a friction clutch.
